CLOTH -ROLL SHAFT FOR LOOll/IS.

SEEGZMIGATION forming part of Letters Patent No. 718,949, dated January20, 1903.

Application filed March 24, 190?. Serial No. 99,582. (No model.)

1.0 aZZ whom it nuty concern:

Be it known that I, ROLAND R. KELLY, a citizen of the United States, anda resident of Villiamstown Station, county of Berkshire, State ofMassachusetts, have invented an Improvement in Cloth-Roll Shafts forLooms, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object the production of novel, simple, andefficient means for preventing longitudinal movement of the cloth uponthe cloth-roll shaft in a loom as the cloth is wound thereupon by theoperation of the take-up mechanism.

In order to obtain smoothly-wound even rolls of cloth with parallel flatends, various devices have been employed, said devices usually acting asguides for the edges of the cloth as it passes around the shaft. I havein my present invention provided the cloth roll shaft itself with meansfor engaging and preventing longitudinal movement of the cloth upon theshaft while being wound, the said means being readily renderedinoperative when it is desired to withdraw the shaft from the completedroll of cloth. In accordance with my invention several of the layers orwindings immediately adjacent the shaft are firmly held fromlongitudinal movement, constituting a true and even core, as it were, onwhich the succeeding layers are readily wound.

The various novel features of my invention will be hereinafterdescribed, and particularly pointed out in the following claims.

Figure 1 is a vertical transverse sectional View of a portion of a loom,taken at the inner side of one of the stands for the clothroll shaft,the latter being shown in section with one embodiment of my inventionapplied thereto; and Fig. 2 is an enlarged elevation and part section ofthe cloth-roll shaft, the cloth-holding means thereon, and the roll ofcloth wound upon said shaft.

Referring to Fig. 1, the loom frame A, breast-beam B, take-up roll T,stands F, (only one being shown,) longitudinally slotted at f for therack-bars g which at their upper ends support the journals g of thecloth-roll shaft G, and the rack-gears g in mesh with the rack-bars, maybe and are all substantially as in United States Patent No.610,636,dated September 13, 1898.

As shown in Fig. 2, the cloth-roll shaft G has a longitudinal recess orgroove 9 therein extending from near one end of the shaft tosubstantially its center, and a slightly-bent elongated arm g isfulcrumed in the recess on a transverse pivot-pin The inner end of thearm is turned out or provided with a substantially radial holdingdevice, shown as a prong g which is normally maintained extended beyondthe surface of the shaft by a suitable spring, as 3 The outer end of thearm is shown as bent oppositely to the prong to form a finger-piece g",which extends through a hole 9 in the shaft and which intersects therecess 9 In order to limit the outward movement of the prong g thebottom of the recess is shown as slightly beveled at g Fig. 2, tosupport the outer end of the arm 9 near the finger-piece. When the web25 of cloth passes around the take-up roll T and thence to thecloth-roll shaft G, the holding device g enters the cloth and preventsit from moving longitudinally on the shaft, and the length of the prongis sufficient to penetrate a number of superposed layers of the clothimmediately adjacent the shaft, as shown in the drawings. This serves toanchor or hold the cloth firmly while the inner portion or core is beinglaid upon the shaft, so that there can be no longitudinal movement ofthe roll 0 of cloth during the winding thereof. When in the rotation ofthe shaft G the prong bears against the surface of the take-up roll, thespring 3 yields temporarily, so that the smoothness of the winding isnot interrupted. After the desired length of cloth has been wound andcut off from the web the roll of cloth and its shaft G are removed, andwhen it is desired to withdraw the shaft from the rollC the attendantpresses on the finger-piece 9 thereby tilting the arm g on its fulcrum,compressing the spring 5 and the prong or holding device 9 is retractedinto the recess g and withdrawn from the cloth, so that the shaft can bepulled out of the roll 0 and replaced in the loom.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Alongitudinally-recessed cloth-roll shaft for looms, aradiallymovable, spring-controlled prong mounted thereon to engage andprevent longitudinal movement of the cloth as it is wound upon theshaft, and means pivotally mounted in the recess to retract said prongagainst the action of its spring to re lease the roll of cloth andpermitwithdrawal of the shaft, said means having a finger-piece accessible atone end of the shaft, whereby the said means may be manually operated.

2. A cloth-roll shaft for looms having a lon ROLAND R. KELLY.
